Patented Sept. 8, 1931 UNITED STATES KARL. SOHWARZ, OF ROSTOCK, GERIIIANY BOAT CLOSET Application filed May 8, 1930, Serial No.

This invention relates to water closets for boats and a main object is to provide a device which is capable of functioning'both above and below the water level.

: A further object is to construct a water closet which is capable of being easily moved to various positions in the boat, which is very important since in boats space is exceedingly limited.

1 It is also an object of the invention to provide controlling means for the closet actuated by the cover thereof.

Still further an object is to provide means whereby both the flushing water and the v incoming supply of water can be controlled from a single valve.

The invention is designed so as to furnish an intermediate chamber which is at certain periods separated from the bowl so'that the contents thereof may be removed through the action of the cover of the bowl.

The various parts of the invention are so designed and constructed as to provide an exceedingly sturdy and simple mechanism E which will not easily become disarranged or inoperative.

With these and other objects in view which will become apparent from the following detailed description, the invention consists in the combination and arrangementof the various parts shown upon the drawings, in which 7 1 Figure 1 is a vertical cross-sectional View with various parts shown in elevation,

Figure 2 is a rear elevational View,

Figure 3 is a top planview of the intermediate receptacle or cylinder, and

Figure 4; is a partial cross-sectional view taken through the connection between the bowl and the intermediate chamber showing the piston construction in the intermediate chamber as well as the operating mechanism for the valve located in said piston.

Referring to the drawings in which similar reference characters denote similar parts in various views, the bowl of the closet is indicated at 2 with the usual cover 1 hinged thereto at the rear thereof by any suitable means. Secured to the outlet end of the bowl 2 is an intermediate receptacle or cyl- 450,825, and in Germany June 7, 1929.

inder 3 having a cover 8 therefor which is secured to the wall of the receptacle 3 by rivets 30 as shown, or in any other desired manner. The outlet of the bowl 2 is indicated at 31 and the cover 8 is provided with an opening 9 which registers with the opening 31 in the bowl 2. i

Sliding in the cylinder or receptacle 3 is a piston 6 furnished with the usual leather the rod 14: which are disposed diametricallyopposite one another upon the piston 6 as shown more particularly in Figure 2. The piston 6 is secured tothe piston rods 13 and 14: by a threaded connection, as shown, or any other suitable manner. A horizontally disposed rod 15 is pivotally connected tothe upper end of the piston rod 14 and also to the upper end of the hollow piston rod 13 through the U-shaped connecting bracket 32. Bearings are provided for the rod 15 inthe standards 20 and the bearings 33 are designed to reciprocate in slots 19 provided in the standards 20 throilgh the medium of the cranks 21 and levers 22which are pivotally connected to the cover lby the screws or other securing means 23. It will be noted that by means of the construction just;described the piston 6 will be reciprocated in the receptacle 3 through the movement of the cover 1 from closed to open position and vice versa. V

A valve 12 is located upon the under side of the piston 6 and is designed to be oscillated so as to close and open the aperture 11 upon movement of the closet cover 1. The valve 12 consists of a plate of substantially pear-shape, as shown more particularly in Figure 3, and the narrow end thereof is secured fixedly to a rod 24 located in the hollow piston rod 13 through the means of the nut 33 and the threaded. end 34 of the rod 24. Interposed between the plate 12 and the nut 33 is a spring 35 holding the plate 12 in tight contact with the washer 10 upon the lower surface of the piston 6. The upper end of the rod 24; terminates in a squared portion 36 to which is fixedly secured a bevelled gear 18 which if desired can be merely a segment. The bevelled gear 18 cooperates with the bevelled gear 17 which is keyed to the shaft 16 and the bevelled gear 17 also may be merely a segment of a gear. As before stated, the rod 15 has secured thereto at each end a crank portion 21 or such crank portion may be integral with the rod 15. Due to this construction it will be noted that upon raising or lowering the cover 1 there is first transmitted by means of the cranks 21 a rotary motion of the rod 15 which is transmitted to the rod 24 by the bevelled gears 17 and 18 so as tooscillal'e the valve 12 away from and over the opening 11. The mechanism is designed so that upon closing or lowering the cover 1 the valve 12 will close the aperture 11 so that upon further lowering movement of the cover 1 the contents of the receptacle 3 \v'll be expelled through the conduit 7 into the valve 27 which communicates with the outside 01 the boat. In the conduit 7 there is provided a one-way valve 5 which is weighted by a weight 4 so as to normally maintain the conduit 7 closed. "he downward motion of the piston 6 however with 30 the valve 12 closing the aperture 11 wil force the valve 5 to open to allow expulsion of the contents of the receptacle 3.

The water utilized in flushing the closet is also attained through the valve 27 through the conduit 26 which acts with the receptacle 25 having under operated means 37 coinprising a piston and plunger with suitable operating valves whereby a supply of water can be forced into the upper forward portion of the bowl 2.

The hull of the boat is partially indicated at 28 to which the valve 27 is secured. The valve 27 is operated through the medium of the handle 88 which will rotate the registering openings for the outlet and inlet conduits 7 and 26 in the sleeves 3 and 27.

A very satisfactory arrangement for the standards 20 is as shown particularly in Figure 2 whereby the bolts 4:0 securing the seat 1 to the bowl are also utilized to secure the upper parts of the standards 20 to the bowl construction. The lower portions of the standards 20 are secured by the screws 41 which at the same time secure the lower flanges d2 of the bowl to the floor.

It is of course evident that if desired, instead of the fixed connection to the floor for the device, a track-way may be provided whereby the closet can be moved out into position and then retracted into a very confined space. It is obvious that such a modification merely requires the necessary tracks and then in place of the rigid connections 7 and 26, suitable flexible hose connections can be made in place thereof.

Suitable stufling boxes 43 are provided around the piston rods 13 and 14 in con tact with the top 8.

It is apparent that various modifications and arrangements may be made in the invention as disclosed above, but it is the intention to include all such modifications as may fall within the spirit of the following claims.

I claim:

1. A closet (ZOIIlPllSlllg a bowl having an outlet, a receptacle secured to said bowl at said outlet, a piston in said receptacle having an aperture registering with said outlet, means for closing said aperture at a predetermined point in the stroke of said piston and means for reciprocating said piston to expel the contents of said receptacle.
